 * The following block of functions and constants is used to control

 *
 * Required: "shield_and_wait_layer.lbi" DreamWeaver library file
 *
 * Synopsis:
 *	DisableUI([show_Please_Wait_Blurb])
 *	EnableUI()
 *	ShieldPersist() - service function called asynchronously to ensure the frame is always on top of the client window
 *	_Center_Layer(aLayerObj) - place a layer object in the center of the client area. 
 *	StartWait() - safely call DisableUI(true)
 *	FinishWait() - hide "Please wait..." blurb.
